I'm hoping someone can easily identify the intake manifold on my 1957 292. I believe it originally came with a 2 barrel, so I don't know what this is. The only identification I've found on it is cast onto the back near the firewall. ECZ-9425-B. The intake is aluminum.
When I took the air cleaner off to get pictures, I realized the manifold vacuum is teed into the fuel pump vacuum line going to the interior heat control valve. I assume this is not original plumbing for the vacuum lines. Is it something I should be concerned about? That tee makes me wonder if the fuel pump vacuum is working well. The other side of the fuel pump vacuum feeds the wipers, and they are pretty close to non-operational.
